The first indications of a non-closed energy balance became obvious in the comparison of EC measurements with Bowen-ratio measurements; the latter close the energy balance by definition. Similar results were found in experiments in Australia in 1981 (Leuning et al.1982) and in June of the years...

28.4. In a closed system, a reactor is filled with reactive adsorbent; and a condenser/evaporator is used to condense the desorbed water vapor during charging process, and to evaporate the liquid water for adsorption during discharging process. In such a system water vapor pressure can be ...
The energy balance for the cooling/heating system is:(14)Hb,in+Qheat=Qcool+Hb,outwhere Qheat and Qcool is the required energy for heating or cooling (kJ h−1). 2.4. Zeolite The zeolite sorption system consists of a wheel system with three separated sections (see Fig. 3): 1) ...
Optimal energy management of electric vehicles using slap swarm optimization and differential flatness control has been proposed. A battery–supercapacitor power system is adopted. Each source is connected in parallel to the DC-bus using DC–DC bidirecti
regarded a smart energy system as an integrated decentralized renewable energy conversion system. The impact of the uncertainty of the energy supply and demand on energy balance can be minimized by smart control, and the interaction between a decentralized system and a smart grid is also optimized ...
